December, 2017
Frans Jongma, Advanced Technology Center

A guided tour through SQL/MX DBS using iTP Webserver
– Requirements
– NonStop System
– iTP Webserver running
– Firefox or Chrome browser
– SQL/MX DBS 3.5.1 installed and configured for DBS
– The demopages installed
– Softlinks for downloadable client software created
– Use mxcreatelinks –s –d /usr/tandem/sqlmx/downloads
– Navigate your browser to http://your_system/mxdbs

Demo Homepage
– This page sows the basic functions for this demo
– This is a demo, it lacks full access control
– You could add user control to a system admin in iTP
webserver
– That way, you do not get self-service, but a system admin
will be able to quickly provision databases for users that do
not require access to the NonStop Operating Environment
via bash or TACL
– Included are a few “DBA” pages that require a valid
NonStop User-ID for verification
– Not a complete solution

A little explanation
– Read this first to learn how to navigate through these
pages
– Click to return to the main page

See what is out there
– Databases are unique on the system they are defined
– Before creating your database, see if your choice of
name has not been defined already
5

Download page for client software
– HPE documentation is written for system managers,
not for end-users
– The same software can be downloaded using this
page
– These are soft links in OSS space that link to Guardian
installation files
– Unlike the Guardian files, the file names are self-
explanatory
– Unzip the zip files, untar the tar files and see what is in them to
decide the next step.
– For example, the mxdm zip files contain the Windows setup
executable files.
6

Create a database
– A database defines the user environment. Its name is used
for
– The name of the catalog
– The name of an MXCS datasource
– For database and schema names, use SQL identifiers (i.e
no spaces, no special characters except underscore _ )
- Password must adhere to Safeguard rules (typically > 6
characters)
- User name is not case-sensitive, and may include special
characters
- Email addresses are OK (frans@hpe.com)
- Windows domain names are OK (emeafrans)
- Users are not case-sensitive unless so defined in the
SYSTEM_DEFAULTS table
- Schema is optional, if not defined, DEFAULT_SCHEMA is
created
- Database create takes about 1.5 -2 minutes
7

Database create results
– When create is finished, the status is reported
– Connection information for host
– Includes the default schema name that is used in MXCS
– Typically port 2100 is used for MXCS (defined during DBS
installation)
– Datasource name to be used when a connection is made
must be in uppercase.
– ODBC and JDBC names are case-sensitive!
8

Time to try the connection
– This slide shows DbVisualizer, a popular tool that
also has a free version with some limited
functionality
– To connect, use the SQL/MX T4 driver
– Driver is downloaded as part t4DriverSoftware.tar
– Configure the driver using the DbVis “Driver Manager”
window
– Tip: In Driver Properties, set
java.sql.statement.setFetchSize 50
9

Use the database
– This example shows how tables are created
– Note the use of Database Compatibility features
– REGION_ID NUMBER
– REGION_NAME VARCHAR2
10

A DBA query (request)
– This is an example of how one might run metadata
queries from a controlled user. This page invokes a
cgi script on the host, and the script will only execute
the query if the user ID and password are valid for
system access.
– Tenant users (such as the created frans@hpe.com)
cannot run these queries.
11

A DBA query (response)
– This is an overview of external users and their
Guardian equivalent
– Also shows to which databases and privilege groups
they belong
12

Another DBA function screen
– Just in case you need to invoke another mxdbs
command
– User ID and password are required
– Except if you press the help button
13

Another DBA function screen (help output)
– The help button invokes the mxdbs –help command
and this is the output.
– Alternatively you can enter the command (or specific
help commands) on the input screen
14

15

– Add a new user to a database
16

– Add a new user to a database
17

A DBA query (response)
– To show that reader@hpe.com has been added as a
user to database DBS_TEST
18

Cleaning up the database
– Free al the resources with a single command
– Drops the catalog and all the objects in it
– Stops and deletes the datasource
– Releases the storage back to the DBS storage pool
– Delete action takes about a minute
19

Database delete results
– After delete action finishes, the result of the action is
displayed.
20

Summary
– SQL/MX DBS makes life easy for a DBA
– The demo shows “how” easy
– Remember, these HTML pages are not secure enough for production purpose
– They show the principle and making access secure is not rocket-science
– HTML and scripts are available
– Working on packaging – send me an email
– No warranty!
